[Abstract]:The research background of this paper is focused on the research and production of refrigeration compressors. With the continuous innovation of refrigeration compressor technology, the production system of this industry is subject to the adjustment of national energy efficiency standards, the development of new products, the sampling and monitoring of shift quality inspection. Due to the influence of the condition of standard machine customer sample delivery and the related restriction of environmental protection technology, there is a higher requirement for the process, technical force and efficiency of the product test. In order to realize the precision of product performance test, a performance measurement and control system of air conditioner compressor based on PLC configuration control is designed, which is commonly called calorimeter. In the process of design and manufacture of the whole equipment, PLC has the characteristics of rich function, stable performance and high reliability, which can adapt to the harsh environment such as high temperature, shock and vibration. Therefore, in the process of industrial production control and management, almost 80% of the work can be accomplished by PLC. At the same time, it can replace relay control device to complete sequence control and program control, adjust pid loop, and also form high-speed data acquisition and analysis system, and implement open-loop position control and speed control. The measurement and control system composed of touch screen display, simple and reliable communication with PLC and PLC touch screen has simple and convenient development environment, high measuring precision and strong anti-interference ability. It is fully suitable for complex factory environment and meets the on-line measurement and control requirements. This system provides a fast and effective method for the development and application of test equipment. The performance measurement and control system of air conditioner compressor based on PLC configuration control is based on solving practical problems. The PLC configuration control system is used to drive the hardware of each industrial and mine generating unit on the platform which is about to happen in the environment of national standard refrigeration. The information collection channel is created, and the remote software collection and information processing system is carried out, which means that the whole product testing process has the functions of scientific, real-time observation and quick obtaining of test results. So that the refrigeration industry to high efficiency, high-level development to a new level. To sum up, the research in this direction has great application prospect and practical significance. In this paper, through the method of the second refrigerant main measurement and the method of refrigerant Flowmeter auxiliary measurement and analysis, the specific hardware platform and software platform are built to realize the accurate measurement of the performance of the refrigeration compressor, and the precision of the measurement is controlled within 5%. The research and realization of this thesis is not only a successful application of the thermodynamic condition to the electric metering analysis, but also to the refrigeration system. At the same time, data analysis intelligent software is used to introduce the huge and complex refrigeration system from the laboratory to the integrated category, which reflects the development trend of data collection intelligence, simple operation, high efficiency and so on. It also provides a new reference method for the design and implementation of refrigeration compressor test platform.
